Answer:
5/12
Step-by-step explanation:
The whole book can be represented as 12/12 because 12 divided by 12 equals one whole ( or one). 1/3 * 4/4(one rewritten) = 4/12 We then need to add this to 1/4 * 3/3 (one rewritten again) = 3/12
4/12 + 3/12 == 7/12
7/12 is the amount Julie did read so we subtract this from 12/12 to get the answer:
5/12
